Biochem/physiol Actions GW833972A is a CB2 cannabinoid receptor agonist with 1000-fold selectivity relative to CB1. It is, however, 15-fold less potent than HU210 for CB2 (Ki 7.8 vs. 0.52 nM). The antitumor compound oxaliplatin induces marked hypersensitivity to cold, heat, and chemical pain stimuli (to the point where oxaliplatin therapy has to be discontinued). The hyperalgesia effect is almost completely blocked by pretreatment with GW833972A.1 GW833972A is a CB2 receptor agonist with 1000-fold selectivity relative to CB1. GW833972A is 15 fold less potent than HU210 for CB2 (Ki 7.8 vs. 0.52 nM). The compound was used to determine the role of CB2 in airway sensory nerve function. |
